IMPROVEMENT IN SAUSAGE-MACHINES.

Specification forming part of Letters Patent To all whom it may concern:

Be it known that I, HUGH P. RANKIN, of the city and county of Allegheny,and State of Pennsylvania, have invented a new and ImprovedSausage-stutter; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing forming a part of this specification, in whichFigure l is a side elevation; Fig. 2, a plan view, partly in section;Fig. 3, a detail transverse section through line g 3 Fig. 4, atransverse section through line as w.

This invention relates to certain improvements in sausage-stuffers; andit consists in a barrel or cylinder pivoted upon trunnions on aframe-work, and provided with an adjustable nozzle. In said barrel movesa piston, which is rigidly attached to a screw-threaded rod, which saidrod is actuated longitudinally in the barrel by means of a bevel-gear,which operates through a revolving sleeve and an adjustablescrew-threaded segment. The latter, by engaging the threads of thepistonrod, converts the rotary motion of the sleeve into a longitudinalrectilinear motion of the piston, and a stud upon the frame-work engagesa longitudinal groove of the piston-rod to keep the latter from turning.

In the drawing, A represents the framework upon which the stuft'eris'constructed, and B is the barrel, which constitutes the body of thestuffer, and in which the sausage is contained. Said barrel is providedwith trunnions a a, which are journaled in open bearings 12 of theframe-work, so that the stuti'er may be either disposed in a verticalposition to facilitate the filling of the same, or placed horizontallyduring the stuffing operation without taking it from the frame. '0 is adetachable nozzle, which is held to the barrel by a fastening, D. Saidfastening is provided with cams e e and slots 0 c, which latter receivestuds d d of the barrel, and the former serve to tigliten the connectionand hold the parts together when turned. E. is

the piston, which is rigidly attached to the screw-threaded rod F. Saidpiston is provided with a valve, f, which opens into the barrel, andadmits the air upon the backward No. 171,631, dated December 28, 1875;application filed J line 12, 1875. l

is to be refilled. G is a revolving sleeve, carrying a cog-wheel, H,which is operated by a pinion, I, and "crank J. The said sleeve ismadewith a smooth bore upon the inside, but

threaded segment, K, which said segment may be ln'adeeither to engage orbe out of contact of the eccentric collar'L and screw M. When saidcollar is turned in one direction the segment K is brought 'intoengagementwith the piston-rod,and a rotation of the crank imparts motionthrough the sleeve to the piston-rod.

When the said eccentric collar is turned in ment is withdrawn from thepiston-rod, and the latter is free to be drawn back with thepistonprevious to filling" the barrel with a new charge of sausage. I

N are supporting-screws or stop projections upon the barrel, which, withits trunnions, support the same in horizontal position *upon the frame,and O is an adjustable arm, which is turned across the edge of thebarrel to hold the same down during the operation of stuffin g.

- Having thus described my invention, what I claim as new is with ascrew-threaded piston-rod, of arevolving sleeve and an adjustableconnection, for gearing together or disengaging the same, as and for thepurpose set forth.

2. The combination of the screw-threaded h, the revolving sleeve G, thethreaded segment K, the eccentric collar 'L, and the gearwheels,substantially as described, and for the purpose set forth.
